Scott Gumbleton has told Essendon that he wishes to be traded to Fremantle, which is well placed to gain the key forward.

Gumbleton told the Bombers of his wish to become a Docker on Wednesday. Fremantle is understood to be offering only pick 54 at this stage, while the Dons have asked for Fremantle's late second-round pick, 33.

Gumbleton had attracted some interest from Port Adelaide, which spoke to his management, but as Gumbleton has not wavered from his wish to join the Dockers, who have already added Melbourne forward Colin Sylvia to their senior list as a free agent and have a need for a tall forward to support 32-year-old Matthew Pavlich.

Gumbleton had considered a move back to his home state of Western Australia last year, before opting to sign a one-year deal with the Bombers, defying the view that Essendon's surfeit of talls - by then including teen prodigy Joe Daniher - meant he would struggle to cement a regular spot in the team.

This year, Gumbleton played seven games for a total of 35 since he joined the Bombers following the 2006 national draft, where the highly touted junior was the No. 2 pick, behind Bryce Gibbs.

He was grounded with a succession of injuries in the first five years of his career - including a back affliction that required surgery in 2011 - but both he and the Bombers persisted in the hope that the popular forward's fortunes would turn, as he returned from the surgery late in the 2012 season and played some impressive football.

The late pick offered by Fremantle was gained when it traded Viv Michie to Melbourne.

The trading period has been held up in recent days, with clubs to learn on Friday what picks they will receive as compensation for free agents. The wait for the confirmation of those picks has made a number of clubs reluctant to commit to players and deals.
